Cannot access staticfiles using Pycharm Community Edition
I am using Pycharm Community Edition and I am new to this and Django as well. I am trying to fetch the background image for my webpage using a CSS file.

Not able to change account details and not sending email once edited - Django
So... My main intention is that when a user edits his/her account and changes the email, the system has to change all the other info except email and send an email to the new email (inputted by the user) with a confirmation link. And once clicked, the system has to redirect the user to another page and change the email for that account. My code was changing all the information (without sending emails) before I added all the email thingy. After I add it, it doesn't change the other details from the account or send a confirmation email. view (I know there is some incomplete code which I need to add): class NormalUserEditView(generic.UpdateView): form_class = EditProfileFormNormal template_name = 'authentication/edit_normalprofile.html' success_url = reverse_lazy('profile') def form_valid(self, form): me = self.request.user.id myuser = User.objects.get(email=self.request.POST['email']) if myuser.email == myuser.email: return redirect('profile') else: current_site = get_current_site(self.request) email_subject = "Email has been changed for", myuser, " - some website" email_message = render_to_string('authentication/email_confirmation.html', { 'name': myuser.first_name, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(myuser.pk)), 'token': generate_token.make_token(myuser), }) email = EmailMessage( email_subject, email_message, settings.EMAIL_HOST_USER, [myuser.email], ) email.fail_silently=True email.send() messages.success(self.request, f'Account Edit: Successful') return super().form_valid(form) def get_object(self): return self.request.user -

I am working on a Django project. It has two Apps, one for explaining the topic, which has its own model, and views, and the second app is a quiz app, which has its own model and view, which will test the ability / learning of the students on each topics.

Django instance in model form
There was a problem, I wanted to make an Django user object creation form, but it doesn't work. Exactly the same view with a different model works fine. I think the problem is how I transmit the data and instance in form. views: @login_required(login_url='login') def CreateRoom(request, pk): topic = Topic.objects.get(id=pk) form = RoomForm(data=request.POST, instance=room) if request.method == 'POST': if form.is_valid(): room = form.save(commit=False) room.host=request.user room.topic=topic room.save() return redirect('home') context = {'form': form, 'topic': topic} return render(request, 'room_form.html', context) forms: class RoomForm(ModelForm): def __init__(self, *args, **kwargs): super(RoomForm, self).__init__(*args, **kwargs) self.fields['themes'].queryset = self.instance.themes.all() class Meta: model = Room fields = '__all__' exclude = ['topic', 'host', 'participants'] -
reverse() doesn't resolve in django-rest-framework
django-rest-framework question: TLDR: reverse() doesn't work when everything I'm being told says it should. OK, Longer version: I have a route that works when I navigate to it. "/api/tag/" I have the route set where all my api routes are set router.register("tag", TagViewSet, basename="tag") TagViewSet is based off a ModelViewSet. If I comment this line out /api/tag/ doesn't work in the browser (so it's the authoritative place). The questions comes when I replace "/api/tag/" in my tests to reverse('tag-list') or reverse('tag:tag-list'). Neither resolves. When I put in (using debug mode) http://localhost:port/api/sldkfjalsdjfalskdjflaksj I get a list of things that resolve which has the line api/ ^tag/$ [name='tag-list'] So I'm wondering what else I can check for to make this reverse() or reverse_lazy() to work. -
How to save uploads models data to the user that is logged in, DjangoRestFramework
I want to post data {photos and caption} and I want it to save to the user that is logged in. I get this error 'Got a TypeError when calling Uploads.objects.create(). This may be because you have a writable field on the serializer class that is not a valid argument to Uploads.objects.create(). You may need to make the field read-only, or override the UploadsSerializer.create() method to handle this correctly.' In serializer.save() I put user = request.user as the argument, but that just gives me the error mentioned above.

Why all the tags not displaying in home.html page?
So here's the problem, I'm trying to display all the tags on the homepage in a dropdown menu but the tags are not being called in base.html. But when I open the specific post itself, the Dropdown menu displays the tags used in that post. Why is that? Can't the tags used in each post be passed on to all pages?

Cpanel Django ERR_TOO_MANY_REDIRECTS on Admin/Auth/User and Admin/Auth/Group Pages
I'm doing a project for a client using Django and have finally installed it on CPanel. Everything seems to be working great, but when I try to access the admin panel, the tables group or user has an error because it says it's doing a lot of redirections. In the admin panel, I just have this: When I try to register something, it loads the page, like this: But when I try to access the tables, it shows me an ERR_TOO_MANY_REDIRECTS, as shown in the following picture: It basically says that it's not working and to try to delete my cookies. I did that, and nothing worked. In the urls.py I only have the admin path so the redirection problem is not from something I miscofigured there. I haven't modified the installation parameters for settings.py besides the Allowed_Host variable to allow the URL of the page, the database connection using PostgreSQL and its working, and the variables of the static files are also working. So I'm feeling deadlocked because I can't find an answer to this and I don't believe I'm the first one experiencing this. If someone knows anything, please let me know. -

django: How to write JavaScript fetch for url with slug parameter?
A django and async newbie here, trying to improve a simple message-board app. I'm sure you've all seen this problem dozens of times, but I'm unable to find a solution... Currently, when a user likes a posted message, it refreshes the whole page. I'd like to use simple JavaScript with the fetch API to prevent this, without having to resort to Ajax, as I've never used it. The problem is, I'm very new to the fetch method as well and I'm struggling to find the correct syntax for the url in the fetch request, as it uses the post model's slug field as a parameter. Like so: urls.py urlpatterns = [ ... path('post/<slug:slug>/', views.FullPost.as_view(), name='boards_post'), path('like/<slug:slug>/', views.PostLike.as_view(), name='post_like'), ... ] models.py ... class Post(models.Model): """ Model for message posts """ STATUS = ((0, "Draft"), (1, "Published")) title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True) author = models.ForeignKey( User, on_delete=models.CASCADE, related_name="board_posts" ) category = models.ForeignKey( Category, on_delete=models.CASCADE, default="", related_name="category_posts" ) created_on = models.DateTimeField(auto_now_add=True) updated_on = models.DateTimeField(auto_now=True) content = models.TextField() post_image = CloudinaryField('image', default='placeholder') status = models.IntegerField(choices=STATUS, default=0) likes = models.ManyToManyField(User, related_name="post_likes") class Meta: # Orders posts in descending order ordering = ['-created_on'] def __str__(self): return self.title def number_of_likes(self): return self.likes.count() def … -
